Abstract (en)
[origin: EP2085501A1] A cathode for hydrogen evolution in an electrolytic cell, comprising a metallic substrate, and a coating consisting of substantially pure ruthenium oxide, is disclosed. The inventive cathode provides enhanced performance and service life under unsteady and intermittent powering, such as powering from solar cells; a process for coating the metallic substrate is also disclosed.
